Vehicle power steering system

摘要

A vehicle power steering system includes a sweep magnet, at least one Hall sensor, and at least one hydraulic-power-steering-system valve. The sweep magnet is fixedly connected to a first end of a twistable steering torsion bar wherein the first end is fixedly connected to a vehicle steering wheel. The at-least-one Hall sensor is fixedly connected to a second end of the steering torsion bar. The at-least-one Hall sensor has an output and is positioned proximate the sweep magnet such that the output is a function of steering wheel torque when the vehicle steering wheel is turned by a driver. The at-least-one hydraulic-power-steering-system valve is operatively connected to the output.
